' I Application filed Kay 9, mod. Serial No. 431,924.

To' all whom it may concern:

' Be it, known that .Bois, a citizen of the United- States, residing at- San' Martin in the county of Santa Clara and State of California, have invented a new and-nsefnl \Vheel-Hnb,-of which the follow-j ing a specification.

This invention relates to wheePhubs and 5 its object is to provide a device of this cha r- '10 acter having a novel arrangement of springs cushioned so as to take up any jolt-ing which may occur withoutthe necessity of utilizing -pneumatic tires or other similar cushioning devices which are entirely concealed within the hub and are therefore protected from dirt and moisture so that their operation will not be impaired.

'With these and other objects in view, the invention consists of certain novel features: of construction'and combinations of parts which will be hereinafter more. -fully de- In the accompanying drawings\tlie pre-' ferred form of the invention has been shown.

dinal seetion through a lab embodying the present improvements. Fig.'2 is a section on line A-B, Fig. 1. -Fig. 3' is-a section on line CD,-Fig. 1.

Referring to the figures by charm-tors of reference, 1 designates an axle having a box 2 fitted thereon and preferably abutting against a flange 3 upon the axle. 'lhe oppo- 5 site end of the box may be screw-threadi-d,

as shown at 4, so as to be engaged by a retaining nut (lpposilely disposed substantially cylindrical hub 'memlwrs T are arranged upon the boxi, one of the members being fixed relative to the box. while the l other member is preferably shifl'able relative thereto. Two of these members are provided and interposed between them is a flanged ring 8 from which the spokes 9 radiate. l" tending through this ring closiu-rits inner edge are openings 10 which are prefenibly enlarged toward their outer ends. and within each of these openings is located a spring rod ll, the ends of \vlnrh are sealed lnsoekets 12 formed in the inner faces of the incin- 1, GEORGE HENRY Du whereby the spokes of the wheel may be Another object is to provide cushioning.

":neal. durable, and etlicient. In sa d drawings-F1 we 1 is a longituhers 7. The nut 5 serves to hold the members 7 in proper position close to the ring 8. One of the members 7 is preferably immovably conuected to the box bv shrinking, it thereon or by providing suitable fastening means, not shown. The other member, however, is preferably removably mounted upon the box but is held against rotation relatively thereto by means of a key 13 seated in registering grooves 14 and 1:3 in the box and the member 7, respectively.

It will be obvious that when any one of the spokes is subjected to longitudinal pressure, as when supporting a load, the ring 8 will be shifted between the members 7 and the springs-11 will be placed under stress and therefore cushion the spokes. be seen that all portions of the cushion are It willclosed by the members 7 and it is practically impossible for dirt or moisture to interfere with the operation thereof. Evenshould any dust get into the members 7 there is sulticient. space therein to permit the free operation of the parts. The cushion-.is designed for use in connection with wheels 'for various purposes, and will be foundto be What is claimed is:

disposed solid, substantially cylindrical hub members upon the box, one of said members being adjustable relative to the other member and both members having series of so kets in their innenor adjoining faces, a spoke-carrying ring interposed between and movable relative to the hub members, said members:ronstitutiug means for preventing lateral tilting of the ring, and aseries of elongated resilient membersseated at their ends within the-sockets of the hub members and disposed at their middle portions within the ring, said ring having a series of apertures lherethrough for the reception of the. resilient (l(\'l('(S.'(.il('ll aperture being tapered from its end toward the center thereof.

In testimony that I claim the foregoing as my own. I have hereto aliixed my signature in the presence of two 'witnesses.
